STEAM-GENERATING MEANS FOR OIL BURNEBS.

Application filed August 18, 1927.

' This invention relates to doors or fronts for use with oil burning furnaces employed in the generation of steam for use among other purposes as an atomizing agent and my improvements are directed to a hollow front or door adapted to contain water and to support a burner, my invention further including means carried by the door and continued into the furnace interior, permitting circulation of the water and providing an extended path of travel therefor through the heating zone. Also my invention comprehends the provision of means contained within the hollow front, for (:01- lecting the steam generated therein and subjecting it to a superheating or drying process prior to its delivery for service.

Still further my invention is inclusive of means provided within the hollow front for the free burning of oil to raise the temperature therein for initially generating steam wherewith to atomize the oil.

Other features and advantages of my invention will hereinafter appear.

In the drawing:

Figure 1 is a front elevation of a furnace front or door equipped with my improvements.

Fig. 2 is a sectional view, taken on the line 2-2 of Fig. 1,

Fig. 3 is a sectional View, taken on the line of Fig. 1.

Fig. 4 is a front sectional elevation.

Fig. 5 is a section on the line 55 of Fig. 1, and

Fig. 6 is a horizontal section on the line 6-6 of Fig. 1.

In said views let 1 indicate a furnace and 2 a door hinged thereto at 3. Secured to the door 2 by screws 4: is a substantially rectangular casing having the back 5, front 6, sides 7, top 8 and bottom 9, the upper portion or chamber A of said casing serving to contain water to be heated, and said portion having a base 10 that is given a corrugated surface to enlarge its heating area. Below base 10 is the firebox B, there being a removable pan 11, placed upon bottom 9, said pan containing moss asbestos or the like which is to be saturated with oil in order to supply the flame for vaporizing the water in the casing.

As an example of heat producing means for use in the fire box a pipe 12 which is extended into the fire box and provided with Serial No. 213,723.

a control valve 13, delivers oil through orifices 13 in its length to the pan 11 from a source of supply not herein shown. Obviously I may employ other heating means in the fire box in place of the oil heating means herein shown. 7

It will be noted in Figs. 2 and 5 that a wall 1 1 extends upwardly from near the bottom of the fire box at an angle that carries it toward the furnace interior and that a battle 15 is extended upwardly from said wall, said wall and battle providing a passageway or flue connection 16 for the ascending products of-combustion, which are thereby caused to pass closely against the back 5 of the water chamber A, thereby subjecting the water in said chamber to heat from said products.

The wall 14- also serves as a partition dividing the fire box with its fine connection from a water chamber 17 provided within .the furnace; said chamber, which connnunicates with the water chamber A in the easing, having connected therewith the open ends 18 of return bend pipes or coils 19, that project into thefurnace, to be subject to the heat influence of a burner operating therein.

Lying within chamber A, above the water level therein, is a pipe 20 that extends outside said chamber to communicate steam to the point of its desired service (not shown) the end 21 of said pipe within chamber A being open to receive the steam. Preferably the pipe 20 is encased within a larger pipe 22, closed at one end 23 and open at its end 2 1 distant from the reception end 21 of pipe 20, so that steam from chamber A must traverse pipe 22, for drying purposes before passing into pipe 20.

Feed water to the chamber A is supplied through a valve 25, a float 26 being connected with the valve for the operation thereof in accordance with variations in the water level.

In Figs. 1, 3 and 4:, I have shown a conoidal passage-way 27 extended centrallyin a casing carried by a furnace door for initially generating steam therein particularly for use as an atomizing agent in conjunction with an oil burner which may be employed for operating the furnace. Also it will be understood that when steam has thus been generated and the furnace is operating normally the continued supply of steam is pro vided by means of the heated coils in the furnace, and then the fire in fire box B can be extinguished.

Variations Within the spirit and scope of my invention are equally comprehended in the foregoing disclosure.

I claim:

1. The combination with an oil burning furnace having a door, of a casing carried by said door, a Water chamber and a fire box in said casing, means for burning fuel in said fire box to generate steam in said Water chamber, and baffle means to direct the burned products from the fire box, in contacting relation with said casing in their flow to the furnace flue,

2. The combination with an oil burning furnace having a door, of a casing carried by said door, a partition arranged in said casing and dividing the same into a water chamber and a firebox positioned below the latter, means for burning fuel in said fire box to generate steam in said chamber, a Wall extending upwardly adjacent the bottom of said firebox and inclining toward the interior of the furnace to define with the casing wall a passageway to facilitate the contact of the ascending products of combustion against the rear of the water chamber.

3. The combination with an oil burning furnace having a door, of a casing carried by said door, a partition arranged in said casing and dividing the same into a water chamber and a firebox positioned below the latter, means for burning fuel in said firebox to generate steam in said chamber, a wall extending upwardly adjacent the bottom of said firebox and inclining toward the interior of the furnace and baflie means extended from the upper edge of said wall, said wall and baffle means defining with the casing wall a passageway to direct the burned products of combustion from the firebox in contacting relation with said casing in their flow to the furnace flue.

4. The combination with an oil burning furnace having a door, of a casing carried by said door, a partition arranged in said casing and defining a conoidal passageway penetrating the medial portion of said casing, and adapted to receive a burner, a. Water chamber and a firebox defined by said partition and the casing wall, means for burning fuel in said firebox to generate steam in said water chamber, and bafl'le means disposed rearwardly of said casing and arranged adjacent the rear portion of said conoidal passageway for directing the burned products from said firebox in contacting relation with said casing in their flow to the furnace flue.
